BRUSH.

SPECIFICATION forming part of Letters Patent No. 231,004, dated August 10, 1880.

Application filed December 29, 1879. i

To all whom t may concern Be it known that we, THOMAS L. GALKINS, of the city, county, and State of New York, and FRANKLIN O. BADGER, of Brooklyn, in the county of -Kings and State of New York, havev invented a new and useful Improvement in Brushes, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a longitudinal central section of a head, showing the manner of drawing said head over the bristles. Fig. 2 is a longitudinal central section of a brush when complete. Fig. 3 shows the manner ofinserting the brush into the capsule. l

Similar let-ters indicate corresponding parts.

This .invention relates to certain improuvements in connecting bristles with a brush; and it consists in combining with a tubular elastic head which surrounds and clasps the bristles a capsule for connecting the tubular elastic head with the handle of the brush.

In carrying out our invention we proceed as follows: We insert the bristles a of the brush into an opening or hole bored for their reception in a piece ot' metal, wood, or other suitable materia-l, A. This piece A is preferably made tapering' or cone shaped. The tubular head B, which may consist of a piece of rubber hose or other elastic material, is` then slipped over the small end ofthe cone-shaped piece A, and is drawn along until it slips over the larger end thereof and clasps the bristles a, as shown in Fig. 2. The ends of the bristles which protrude from the lower end ofthe head B are then cut o iiush with said lower end, while the other ends of the bristles are left protrudin 0'.

In order to facilitate the drawing ofthe head B over the eolie-shaped piece A, the smaller end of said piece A may be clasped in a vise when the head B has been pulled along far enough to leave said smaller end exposed, after which said head B can be s lid along with considerable force. By oiling the surface of the cone-shaped piece A the elastic head will glide along more easily.

the bristles, is then inserted into a capsule, (1

from below, Fig. 3. The upper end of the capsule C is provided with a lip, b,-against which the head B abuts, while the bristles a protrude. A disk-shaped piece of metal or other suitable material, d. is then pressed up against the lowerend ofthe head E, and is held in place by apin, c, which is passed through holes in the capsule C. Said pin c may be provided with a notch, so as to clasp the sides ot' the capsule (l, and prevent said pin c from slipping or falling out, as shown in Fig. 3.

The lower end of the capsule C may he pressed onto a spindle or handle with a conical head, or said capsule may be tapped and screwed onto the end of a spimlle-ma-ndrel or onto a handle. Of course we do not limit ourselves to this precise form of capsule G, since several forms of capsules may be used which willanswer the purpose of retaining the head B.

The advantages of this brush a-re that it is cheaper, since the head B and capsule C can be used for a long time wit-hout wearing out, while the bristles a., when worn out, can be readily replaced.

ln order to press the disk dtlrmly up against the lower edge of the head B, Fig. 3, we make use of a cylindrical shaped plug ot' wood, metal, or other lit material. This plug is provided with a notch cut into one end thereof', and is pressed into the capsule O, so that said notch corresponds to the opening in said capsule G through which the pin o is to pass. Vhen the disk d has thus been lirmly pressed up and the head B compressed against the lip I), the pin .c is inserted, after which the plug is withdrawn. The notch in the pin o is then caused to clasp the sides of the capsule C by the reaction of the elastic head B, thus preventing said pin c from falling out.

This manner of construction can be applied to paint-brushes, feather-dusters, or any kind of brush or buff for polishing or painting pur-v In testimony whereof We have hereunto set Io poses. our hands and affixed our seals this 23d day \Vhat we ela-im as new, and desire to secure of December, 1879. by Letters Patent, is-
